Freddie Mac is a gatekeeper in the mortgage market. In many cases, the taxpayer-owned mortgage company controls who qualifies to refinance a mortgage and who doesn't. Well, NPR has learned that Freddie Mac has been making financial wagers, betting against American homeowners being able to refinance. And now some lawmakers want to put a stop to it. NPR's Chris Arnold has been reporting this story in partnership with ProPublica.org. He has this report.

The contest for the seat held by Sen. Jon Tester, a Montana Democrat, is one of the potentially close 2012 races that could ultimately decide whether Democrats maintain control of Congress' upper chamber.
